 a rust application to scrobble your currently playing song on last.fm with mpris
 
-upd 2024-08-27: i'm adding a home-manager module, eventually!
-
 ## limitations
 
 unfortunately, because of how most mpris players work, the [Track_Id](https://specifications.freedesktop.org/mpris-spec/latest/Player_Interface.html#Simple-Type:Track_Id) (unique identifier for every song in the tracklist) object is very rarely supported, or, if supported, implemented incorrectly (looking at you, [Cider](https://cider.sh/)) meaning it is impossible to tell if the track has been played twice in a row. this means you cannot have succssive scrobbles of the same song, sorry! besides this, i'd say the program is feature complete.
